FABRIC-TREATING- DEVICE.

Application filed November 22, 1917.

T0 all whom t may concern.'

Be it known that I, HOWARD M. DUDLEY, a citizen of the United States, residing in the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Fabric-Treating Devices, of which the following is a full, clear, and eXact speci fication.

My invention relates to fabric treating devices and refers particularly to those de.- vices suitable for treating wound fabrics with liquid, steam or air.

One object of my invention is a device whereby a series of. Wound fabrics may be subjected simultaneously to equal and uniform treatment with liquid, steam or air.

Another object of my invention is a device in which fabric of any width may be subjected to equal and uniform treatment with liquid, steam or air.

Another object of my invention is a device in which liquid, steam or air may be passed in opposite directions through a series of wound fabrics to produce even and uniform results.

Another object of my invention is a device in which Wound fabric may be maintained in a fixed position during the passage of liquid, steam and air through-it in opposite directions.

Another object of my invention is a device in which the condition of the fabric may be determined without opening the device, interrupting the operation or disturbing the fabric. A

These and other objects of the device of my invention will be evident upon a consideration of my specification, drawingsand claims.

A number of difliculties present themselves in the treatment of wound fabrics such as Idyeing, crabbing, steaming and bleaching. All portions of the fabric must receive equal treatment in order that the interior, exterior and edges of the fabric may be uniform, equal penetration must exist in all parts, and the device must be capable of treating fabricv of varying widths. In addition to these requirements, it is advantageous to treat a number of Wound fabrics simultaneously in order to save time and p labor and insure uniformity of results. Further, it is essentialthat the condition of the treated fabric be capable of judgment Specification of Letters Patent.

The particular form of the device of my invention shown in the accompanying drawings, comprises a body member 10, within which is a series of fabric chambers 11, 11,

1 1. A bottom member 12 is attached to the iange` 13 of the body 10 by means of the bolts 14, 14, 14 passing through the flange 15 of the bottom 12. The bottom 12 comprises an upper liquid chamber 16 and a lower liquid chamber 17 Within the bottom 12 is a series of tubular openings 18, 18

formed by. the walls 19, 19, the tubular openings 18, 18 Connecting the liquid chamber 17 with the upper portion of the liquid chamber 16 and being situated centrally of the fiber chambers 11, 11. The upper portion of each annular wall i19 has an annular recess formed by the members 20 and 21 for puroses described later. The chamber 16 is Connected to the pipe 22,'carrying the valve 23, connected tothe pipe 24 which in turn is connected to the discharge chamber of the 31, carrying the valve 32.v The lower portight oint.

tion of thel reserve tank 30 is connected to the receiving chamber of the pump 25 by means of the pipe 33 carrying the valvev 34.

y The receiving chamber of the pump25 is also connected to the pipe 35 carrying the -valve 36, connected to a dissolving tank, not

shown.

The fabric carrying means comprises a forammous core formed by a series of parallel spaced bars 40, having outer serrated edges 41., 41, carried by the hollow annular members 42, 42. Slidable over the foramif nous core are two flange members 43, 43, the lower arms 44, 44 of which abut upon the member 42 to form a water-tight oint. Each member 42 carries an offset 45, which is connected to the offset 46 of the flange 43 by means of a series of right and left turnbuckles 47, 47, thus allowing the flanges 43, 43 to be fixedly positioned at predetermined distances from each other. The bottom annular member is capable of being positioned between the members 20 and 21 to form a water-` The upper end of each core is closed by means of a cap 48. A removable top 50 is capable of being attached to the flange 51 of the body 10 by means of thel bolts 52, 52. Threaded through openings in the top 50 is a series of set screws V53, 53, each being capable of being positioned within a recess within the cap 48. The flanges 43, 43 have a .series of slots 90,90 in their outer positions,

into which the blades 91, 91 having the offsets 92, 92 may be fitted. The blades 91, 91 rest against the fiber 100 and are pressed inwardly by means of the clamping members 93, 93 and the clamp screws 94, 94.

A smaller testing device, proportionate to l the large device and having one core therein,

is exterior of the device, and in the drawings, parts similar to those of the larger device are designated by prime numerals.

The chamber 16 is connected to the chamber 16 by the pipe 60 carrying the valve 61, and the chamber' 17 is connected to the chamber 17 by the pipe 62 carrying the valve 63. The fiber' 100 within the testing device may be examined by removing the top 50 yand withdrawing the fiber-carrying member.

A pipe 80, carrying Athe valve 81, connects the discharge chamber of the pump 25 with a source of fresh water supply, and the drain pipe 82, carrying the.valve 83, is connected to the chamber 17. The pipe 84,

, carrying the valve 85, connects the pipe 24 with a source of steam. i'

fabric chambers,

. 43, 43 and forced against the fiber 100 by means of Ithe clamping members 93, 93.` The top 50 is removed, a wound fabric carrying member inserted in each fabric chamber 11, 11 so that the bottom member 42 fits between the members 20 and 21, the top 50 vattached to the body 10, and the set screws 53, 53 set to hold the wound fabric in a fixed position. The -testing machine is f removed, fabric 100 introduced therein and the testing device replaced.;4 All of the valves are closed with the exception of valves 36, 27, 29, 61 and 63 and the pump 25 started. The liquid thus passes from the dissolving tank, not shown, into the pump 25, through the pipes 24 and 26 into the liquid chamber 17 and thence through the openings 18, 18 into the center of the cores and thence outwardly through the fabricv 100 wound thereon, into the fiber chambers 11, 11 and the liquid chamber 16, from which 'it passes through the pipes 22 and 28 into the reservetank 30. When sufficient liquidy has been introduced, vvalve 36 is closed and valve 34 is opened, the liquid thus passing continuously 1n the direction indicated. At the same time the liquid takes a similar course through the testing device and the fabric 100 therein. When it is desired to pass the liquid in the opposite direction, the valves 27 and 29 are closed and valves 23 and 32 opened. Then the liquid passes froml the pump 25 through the pipesl 24 and 22 into the liquid chamber 16 and the and thence inwardly through the wound fabric 100 into the centerof the core and then through the openings 18, 18, the liquid chamber 17, the pipes 26, 31 and 28 into the reserve tank and then through the pipe 33 for continuous circulation. At the same time the liquid passes through the testing device and the fiber 100 therein in a similar direction. The liquid may be drained from the deviceby opening i the valve 83 of the pipe 82. Fresh water as shown and described, all of which may 'be lvaried` without going beyond the scope of my invention as described and claimed.
